Daniel Ricciardo reckons Red Bull tweaks will close gap to Williams

The Red Bull-Renault alliance has had a troubled F1 season so far with a string of power unit failures forcing Ricciardo and Daniil Kvyat to take grid penalties for last Sunday's Austrian Grand Prix.

Ricciardo rescued a point with 10th but Kvyat finished adrift in 12th as Red Bull saw the gap to third-placed Williams grow to 74 points.

But following a relatively trouble-free day of testing in Austria, halted only briefly because of a brake pedal problem, Ricciardo is expecting a stronger performance at Silverstone.

"I'm hoping for a better weekend than here," he said.

"I think naturally the circuit will suit our car, let's say the characteristics of what we have. "We will have some updates, some aerodynamic pieces, which should be good so I'm excited for this.

"I think we'll back more or less in that top-seven group, probably just behind the Williams.

"I don't think Mercedes or Ferrari yet, but hopefully we can be close to Williams."

Ricciardo said Red Bull learned a lot from the final day of testing, when he completed more than 100 laps, and says it understands why his brake pedal stuck towards the end of the session.

"We had a small failure inside the car, the brake pedal got stuck on and then the brakes overheated and then caught on fire," Ricciardo explained.

"We know why it happened, which is important, and we did lots of laps so it was a good day.

"We made some bigger changes today to explore the limits of the car and try and extract more potential from it."
